chromatophore

  1. (also called chromoplast) a pigmented PLASTID of plant cells which may be green due to the presence of chlorophyll or differently coloured because of the presence of CAROTENOID pigments. CHROMATOPHORES are often CHLOROPLASTS in which the pigment has broken down, as in the ripening of fruit.
  2. (in animals) a cell with pigment in the cytoplasm which can be dispersed or concentrated so changing the colour of the animal as a whole. Animals with this characteristic include frogs, chameleons, cephalopods.
  3. (in photosynthetic bacteria and CYANOBACTERIA) a membranous structure carrying photosynthetic pigments.

In leopard mutants, the yellow xanthophores reach out toward the black cells but don't chase them.
Chromatophores include xanthophores associated with the melanophores on the dorsal and ventral midlines and a single erythrophore at the base of the caudal fin.
Thunnus thynnus did not have xanthophores from hatching to the preflexion stage.
Its bluish-pigmented cells, iridophores, reflect light through yellowish cells (xanthophores).
At hatching, the body and yolk are covered with stellate and dendritic xanthophores, with a heavy concentration on the dorsal and anal finfolds posterior to the yolk.
